| Summary: | (+20C, -20% VP) caused a 9% increase in ET. Effects of (Gossypium hirsutum L.) were assessed by using the WXGEN 10% decrease in Rs, increases in LAI of 8.5% for cotton and 25 years, in combination with gradual ︢15% changes in VP, a 3.5% for sorghum, and reductions in stomatal conductance by 3.75% for cotton and 6.75% for sorghum from the control case among scenarios. and in combination. Evaporation (E) and transpiration (T) and leaf area index (LAI) were altered ︢20% individually, atmosphere. Effects of climatic change on surface water and climate generator model to create weather data for several E and 3.0% (11 mm) in T. The inputs that affected T (from energy balances of sorghum (Sorghum bicolor L. Moench) were ENWATBAL. A gradual 0.50C increase in air temperature over evaluated by the dynamic simulation model ENWATBAL. Daily Global climatic change may be occurring due to the increase global irradiance (Rs), vapor pressure (VP), wind speed (U) gradual climate change on water balance of sorghum and cotton greatest to least influence) were Rs, LAI, U, and VP, while E important factors affecting ET. Warmer and drier weather Limited rainfall was main reason for the small differences of carbon dioxide and other "greenhouse" gases in the plant growth and stomatal response had little effect on ET. predicted that climate change and CO2 induced changes in scenarios in Bushiand and Lubbock, TX, that were used in the scenarios on both sorghum and cotton ranged 0.2% to 1.1%. temperature resulted in an average increase of 2.9% (6 mm) in temperature was varied ︢30C from the control case, while The changes in ET from the control case over 25 years on all the inputs were integrated, temperature and VP were the most was affected most by LAI, followed by VP, U, and Rs. When were calculated separately. One degree incremental changes in were studied. ENWARTBAL simulations over a 25-year period |
